Homemade Easy Slime

Homemade Easy Slime is the perfect Sensory Play Idea for Preschoolers! |


  • 1 bottle glue
  • Baking soda
  • Contact lens solution
  • Liquid watercolors or food coloring, optional


  1. Pour the glue into a large mixing bowl and add 1/2 tablespoon baking soda. Stir together with a spoon until the ingredients are as blended as possible. Add food coloring or liquid watercolors until desired color is achieved.
  2. Add 1 1/4 tablespoons contact lens solution and mix again until as blended as possible. You might have a few pockets of ingredients that clump together. This is okay. You’re trying to get the mixture to blend into one large mass.
  3. Once you have a mass of slime, then start kneading it and stretching it by hand. This will help evenly distribute the ingredients. If the mixture is too sticky, add a little extra contact lens solution in increments of 1/4 teaspoons. If the slime is too runny, then add more baking soda in increments of 1/4-1/2 teaspoons. Continue to knead, stretch, and fold the slime until desired consistency is reached.
  4. Store in an airtight container for several days.


The more you knead and stretch the mixture, the more it will form into slime. If adding extra baking soda or contact lens solution, do so in small increments as a little bit will go a long way, and you may be closer to achieving play-ready slime than you think. ALSO, if you end up with a little glue stuck in the bottle, prop it upside down on the counter for a few minutes. You’d be surprised how much glue you can eke out of those last drops.
